The halacha is that they should be attracted to each other and not find each other ekeldik. Of course this makes sense. But what does not make sense is the concept that they are entitled to the most beautiful girl in the universe and that they should seek that one out. Who says that Hashem has chosen that for their bashert? That is very conceited of them don’t you think? That should not be the most important criteria for marriage.
A young woman can learn to enhance her looks with makeup. She can change her hairstyle with her new sheitel, And the same goes for a young man by changing his glasses or wearing lenses and with a different haircut. And of course changing the style or even color of clothing can make a huge difference in appearance. But you can’t change a selfish person to be generous, you can’t change a sharp tongue to be a sweet talker, etc.
